i too got a greenhouse on freecycle. my advice would be - get someone else to do it!!!! i sent my brothers as i had just given birth. i was lucky that my brother borrowed his works lorry to put it on the back without taking it to bits (apart from the glas obviously) remember how the window that you can open goes. it took us ages to find out that it slid down a groove.

but freecycle is great for this stuff, i was also gifted seed trays. i once saw a rotorvator but was sadly too late!
